# This checks for an issue with internal calls and BAT (BOLT address
# translation). BAT needs to map every output block back to an input
# block, but passes that introduce new blocks (such as validate
# internal calls) might create new blocks without a mapping to an
# input block.

# REQUIRES: system-linux,bolt-runtime

# RUN: llvm-mc -filetype=obj -triple x86_64-unknown-unknown %s -o %t.o
# Delete our BB symbols so BOLT doesn't mark them as entry points
# RUN: llvm-strip --strip-unneeded %t.o
# RUN: %clang %t.o -o %t.exe -Wl,-q

# RUN: llvm-bolt --enable-bat %t.exe --relocs -o %t.out | FileCheck %s
# CHECK: BOLT-INFO: Wrote {{.*}} BAT maps

# RUN: llvm-bat-dump %t.out --dump-all | \
# RUN:   FileCheck %s --check-prefix=CHECK-BAT-DUMP
# CHECK-BAT-DUMP:  BAT tables for {{.*}} functions
